Step 2: Make a charge transaction with the twint resource that you created.

Step 3: Forward the customer to the redirectUrl that is displayed in the charge response.

Step 4: Once the customer makes the payment on their bank portal, redirect the customer to the returnURL specified in the initial charge call.
